[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture for hanging a lighting fixture such as a lamp or a spotlight on a suspension rail mounted on a ceiling.

[0002]

2. Description of the Related Art Conventionally, when a lighting device such as a spotlight is suspended from a suspension rail mounted on a ceiling, for example,
A suspender with a grip is attached to the lighting fixture, and the grip body of the suspender is clamped and attached to a suspending locking portion of a suspending rail. Then, a power cord is inserted by inserting a plug of a light cord from the ceiling into a socket of the lighting equipment.

[0003]

However, this method of taking a power supply is inconvenient when the lighting fixture needs to be moved along the rail, because the electric light cord needs to be in the way or needs to be changed. For this reason, a suspension rail has been developed in which conductive pieces are arranged along both sides of a suspension locking portion of a lighting fixture or the like in the suspension rail so that power can be taken at any location on the rail. ing. An object of the present invention is to provide a lighting fixture hanging fixture for hanging a lighting fixture such as a light or a spotlight on the suspension rail.

[0004]

According to the present invention, there is provided an insertion plug having a connection terminal on an upper side and a socket conductive member on a lower side, and an openable / closable grip body, and an insertion plug mounting recess on one side. A lighting device, comprising: a set of case halves provided with grip body mounting recesses in parallel on the other side, wherein the insertion plug and the grip body are sandwiched between the case halves and fixed with mounting bolts. It is a hanging fixture.

[0005]

In order to suspend a lighting device such as a spotlight or a lamp on a suspension rail, first, rotate the lock member to loosen the screw with the lead screw portion of the operation rod, and move the operation rod upward. Press to open the grip body. Then, insert the connection terminal into the conductive piece of the suspension rail, rotate the lock member in the opposite direction from the front and tighten it, and the operating rod will descend, the grip body will close, and the suspension will be suspended with the grip body. The suspension locking portion of the suspension rail is clamped, and the suspension fixture is fixed to the suspension rail. When the socket insertion portion attached to the lighting fixture is inserted into the socket portion below the insertion plug and rotated, the socket insertion portion comes into contact with the stopper portion and engages with the support portion to conduct with the socket conductive member. Thus, the lighting fixture is securely fixed to the hanging fixture, and power can be taken from the conductive piece. When moving the luminaire along the suspension rail, remove the luminaire from the suspension fixture, rotate the lock member to release the gripping state of the gripping body to the suspension locking part, and connect The terminal may be pulled out and the same suspending operation as described above may be performed.
